What is the function of the temperature blending valve in the SDS?

The temperature blending valve in the SDS (System Delivery System) serves the important function of mixing hot and cold water to achieve a precise temperature, commonly set at 77 degrees Fahrenheit. This controlled mixing is essential for creating dialysate with the appropriate temperature for patient comfort and to ensure effective dialysis treatment. Maintaining this specified range is crucial because temperature can significantly impact both the efficacy of the dialysis process and the physiological effects on the patient.

Other functions such as cooling down the dialysis fluid, regulating pressure, or boiling water for sterilization are not the primary purposes of the blending valve. Cooling is a separate process that may occur later in the system, while pressure regulation is typically managed by other components within the system. The boiling of water for sterilization is also not performed by the blending valve, as this function requires different equipment and processes to ensure proper sanitization. Therefore, the blending valve's specific role in mixing to 77 degrees Fahrenheit is critical for effective dialysis delivery.
